Abstract Background: Temporomandibular disorder (TMD) is a broad term that encompasses pain and/or dysfunction of the masticatory musculature and TM joints (TMJs). Its most important feature is pain, followed by limited jaw movement, and joint sounds. When it progresses to a chronic condition, the symptoms are extremely difficult to manage, often requiring multiple interventions. Case presentation: Our patient, a woman in her 50s, developed TMD after a traffic accident that occurred 30 years previously. The patient presented with severe trismus due to TMJ pain (maximum mouth opening was 20 mm). She was scheduled to undergo extraction of a right lower molar and three upper anterior teeth owing to progressing caries. However, it was anticipated that the treatment would be difficult since the patient could not open her mouth adequately. Therefore, we considered relieving the trismus to facilitate dental treatment. Based on the findings, the cause of the TMD was considered to be pain in the masticatory muscles during mouth opening. Ultrasound-guided inferior alveolar nerve block (IANB) was performed on both sides using ropivacaine. Three minutes after the IANB, the pain during mouth opening disappeared and the maximum mouth opening improved to 40 mm. Dental treatment could be performed without difficulty, and the patient could maintain the mouth open throughout the treatment.Conclusions: Treatment methods for chronic TMD are limited and it is necessary to consider the exact aetiology before deciding upon a treatment option. In our case, ultrasound-guided IANB proved to be an effective modality for relieving TMD-related trismus.

Abstract Background Temporomandibular disorder (TMD) is a broad term that encompasses pain and/or dysfunction of the masticatory musculature and TM joints (TMJs). When TMD becomes a chronic condition, the symptoms are extremely difficult to manage and require multiple interventions. Case presentation A woman in her 50s developed TMD after a traffic accident 30 years ago. The patient presented with severe trismus due to TMJ pain and a maximum mouth opening of 20 mm. Ultrasound-guided inferior alveolar nerve block (IANB) was performed with ropivacaine. After IANB, the pain during mouth opening subsided and the maximum mouth opening improved to 40 mm. Dental treatment could be performed without difficulty and the patient could keep her mouth open throughout the treatment. Conclusions Treatments for chronic TMD are limited and it is necessary to identify the precise etiology before choosing a treatment option. In this patient, ultrasound-guided IANB proved to be effective in relieving TMD-related trismus.

Blinded techniques to desensitize the inferior alveolar nerve (IAN) include intraoral, angled, and vertical extraoral approaches with reported success rates of 100%, 73%, and 59%, respectively. It has not been determined whether an ultrasound-guided extraoral approach is feasible. Further, the fascicular nature of the inferior alveolar and lingual nerves of the horse has not been described. The objectives of this study were to describe a low-volume ultrasound-guided vertical extraoral inferior alveolar nerve block technique and to describe the fascicular nature of these nerves. An ultrasound-guided approach to the IAN was conducted with a microconvex transducer and an 18-G, 15-cm spinal needle using a solution containing iodinated-contrast and methylene blue dye. Accuracy was assessed by contrast visualized at the mandibular foramen on computed tomography (CT) and methylene blue dye staining of the nerves on gross dissection. Sections of inferior alveolar and lingual nerves were submitted for histological analysis. Assessment by CT and dissection determined success rates of 81.3% and 68.8%, respectively; 68.8% of injections had inadvertent methylene blue dye staining of the lingual nerve. Nerve histology revealed both the inferior alveolar and lingual nerves to be multifascicular in nature. Mean fascicle counts for the inferior alveolar and lingual nerves were 29 and 30.8, respectively. The technique is challenging and no more accurate than previously published blinded techniques. Any extraoral approach to the IAN is likely to also desensitize the lingual nerve.

Background/Aim. Surgical extraction of lower third molars is followed by mild or severe postoperative pain which peaks at maximal intensity in the first 12 hours and has a significant impact on a patient?s postoperative quality of life. The use of long-acting local anaesthetics is a promising strategy to improve postoperative analgesia. The aim of the present study was to investigate analgesic parameters and patient satisfaction after using 0.5% levobupivacaine (Lbup), 0.5% bupivacaine (Bup) and 2% lidocaine with epinephrine 1:80,000 (Lid + Epi) for an inferior alveolar nerve block following lower third molar surgery. Methods. A total of 102 patients (ASA I) were divided into three groups, each of which received either 3 mL of Lbup, Bup or Lid + Epi. The intensity of postoperative analgesia was measured using a verbal rating scale (VRS). The total amounts of rescue analgesics were recorded on the first and during seven postoperative days. Patients satisfaction was noted using a modified verbal scales. Results. A significantly higher level of postoperative pain was recorded in Lid + Epi group compared to Bup and Lbup groups. No significant differences were seen between Bup and Lbup, but a significant reduction in the need for rescue analgesics was seen postoperatively in both Lbup and Bup (50%) in comparison with Lid + Epi (80%) in the first 24 hours. The same significant trend in rescue analgesic consumption was recorded for seven postoperative days. Patients? overall satisfaction was significantly lower for Lid + Epi (10%) than for Lbup (56%) and Bup (52%). Conclusion. The use of a new and long-acting local anaesthetic 0.5% levobupivacaine is clinically relevant and effective for an inferior alveolar nerve block and postoperative pain control after third molar surgery. In our study Lbup and Bup controled postoperative pain more efficiently after lower third molar surgery compared to Lid + Epi.

Abstract Objective To compare the effectiveness and complications of intraligamentary anesthesia (ILA) with conventional inferior alveolar nerve block (IANB) during injection and dental treatment of mandibular posterior teeth. Materials and methods In this randomized, prospective clinical trial, 72 patients (39 males, 33 females), scheduled for dental treatment of mandibular posterior teeth, were randomly allocated to ILA group (n = 35) received ILA injection or IANB group (n = 37) received the conventional IANB. Our primary outcome was to assess pain and stress (discomfort) during the injection and dental treatment, using the numeric rating scale (NRS) from 0 to 10 (0 = no pain, 10= the worst pain imaginable), whereas recording 24-h postoperative complications was our secondary outcomes. Results Patients in ILA group reported significantly less pain during injection when compared with IANB group (p = 0.03), while pain during dental treatment was similar in both groups (p = 0.2). Patients in both groups also reported similar law values of discomfort during treatment (p = 0.7). Although no signs of nerve contact or any other postoperative complications were observed, five patients in IANB group (none in ILA group) reported temporary irritations. Conclusion This study showed equivalent effectiveness of both intraligamentary anesthesia and conventional inferior alveolar nerve block, for pain control during routine dental treatment of mandibular posterior teeth. Nevertheless, ILA showed significantly less pain during injection. No major postoperative complications in both groups were observed. Clinical relevance ILA could be considered as an effective alternative for routine dental treatment. Trial registration NCT04563351
